Adblock Plus for Internet Explorer

Although you might not expect it, Internet Explorer is still the world's second most popular browser with hundreds of millions of daily users. We developed Adblock Plus for Internet Explorer precisely for those users — so that they can finally experience the web without annoying ads.

Developing an extension for Internet Explorer is challenging — that’s one of the reasons there are not as many extensions on Internet Explorer as on Mozilla Firefox, Google Chrome and Opera. The installation of Adblock Plus for Internet Explorer is different than on other browsers. Usually, the extension is directly added to the browser; however, for Internet Explorer you need to install it through a so-called setup program. But don’t worry: it takes under 30 seconds to install Adblock Plus for Internet Explorer. Just click on the green button above called “Install for Internet Explorer” to protect yourself from annoying advertising.

Current limitations: Due to the limitations of some of the fragmented versions of Internet Explorer, Adblock Plus currently doesn’t work for:

Metro Mode of Internet Explorer in Windows 8

Internet Explorer in Windows RT

Adblock Plus for Safari

With the release of Adblock Plus for Safari in January 2014, the ABP browser family became complete. From that point on, our extension has been available to all the major browsers: Mozilla Firefox, Google Chrome, Internet Explorer, Opera and Apple Safari.

Adblock Plus for Safari uses the same codebase as the Chrome and Opera versions. Although this made the development of the adblocker much more complex, there are certain key advantages. For instance, it shares the same codebase, any changes or improvements made to one of these browsers will automatically land in Safari, ensuring an experience that is always up-to-date.

In contrast to Chrome and Firefox, Safari comes with a few innate limitations. Because these are built into the browser, they affect every add-on available for Safari - and ours is of course no exception. These limitations exist because it is not possible to get “deep” access to the Safari code, like we can with other browsers. Bottom line: there are some facets of Adblock Plus for Safari that cannot function optimally. For example, it is not possible to block ads in “third-party plugins” like video players or to block the so-called XHR requests. Usually this would mean that YouTube video ads cannot be blocked. But because of some very smart workarounds, Adblock Plus can block these annoying video ads in your Safari browser.

But, overall, Adblock Plus for Safari is a good as it gets ad-blocker for Safari and will block all annoying banners and video ads.

Currently, Adblock Plus is supported by Safari 6.0 and higher.
